303 mike hit it pretty much on all accounts, but it's not a #1 Sporting rifle , its a Long Range Express from the mid 80's. 34" std tube NO rear barrel sight or dovetail. The tube sight up frt has a post and way to big ball for fine shooting at more than 200 yds. The rear as he said is a std Sporting tang sight that came on the LRE. A #1 would have atleast a dovetail for a rear barrel sight and only 30" long with a blade frt. My money is on a 5-7k serial number with Shiloh Rifle Co Big Timber Montana on the left side of the rec and C . Sharps Arms Co. with {Old Reliable} tm to the left of the C. Sharps..on the top barrel flat. Put you in the 83-87 time range . Back then they came with real case hardening and nice wood. (options today) tell us the serial# exam 70xx or B60xx or 60xxB that will help date it. I believe that exact gun in 84 retailed for $790.00 got anymore questions? Magnum man
